added g_list_nth_prev() which walks ->prev instead of ->next.

Tue Apr  3 13:46:22 2001  Tim Janik  <timj@gtk.org>

        * glist.[hc]: added g_list_nth_prev() which walks ->prev instead
        of ->next.

        * gpattern.[hc]: added shell-style pattern matching code from beast,
        derived from the gtk_pattern_*() code, but with a couple of bug fixes
        and a number of optimizations.

Tue Apr  3 14:06:00 2001  Tim Janik  <timj@gtk.org>

        * gparam.[hc]: added g_param_spec_pool_list() to list pspecs per
        owner_type. the pspecs are not referenced, so the caller is
        supposed to have some idea about owner_type not randomly
        nuking his pspec's. if this is going to provide problems in
        the future, we can either auto-ref the pspecs, or add a
        _foreach variant, though the latter would have to invoke
        the callback while pspec's mutex is acquired, so i just
        went for the _list variant for now.

        * gclosure.h (G_CALLBACK): made GCallback a void (*) (void) fucntion.
